Removal and Installation
REMOVAL
- Disconnect each joint and mounting rubber.
- Remove heated oxygen sensor 2 (1) using Tool (A).
Tool number : KV10114400 (J-38365)
CAUTION:
- Discard any heated oxygen sensor which has been dropped
from a height of more than 0.5 m (19.7 in) onto a hard surface
such as a concrete floor; use a new one.
- Before installing new heated oxygen sensor, clean exhaust
system threads using oxygen sensor thread cleaner and
approved anti-seize lubricant.
Oxygen sensor thread cleaner : J-43897-12
Oxygen sensor thread cleaner : J-43897-18
INSTALLATION
Installation is in the reverse order of removal.
CAUTION:
- Always replace seal bearings with new ones when reassembling.
- Discard any heated oxygen sensor 2 which has been dropped onto a
hard surface such as a concrete
floor. Use a new one.
- Before installing a new heated oxygen sensor 2, clean exhaust
system threads using the oxygen
sensor thread cleaner and apply anti-seize lubricant.
- Do not over tighten heated oxygen sensor 2. Doing so may cause
damage to the heated oxygen sensor
2, resulting in the “MIL” coming on.
- Prevent rust preventives from adhering to the sensor body.
- If heat insulator is badly deformed, repair or replace it. If
deposits such as mud pile up on the heat
insulator, remove them.
- When installing heat insulator avoid large gaps or interference
between heat insulator and each
exhaust pipe.
- Remove deposits from the sealing surface of each connection.
Connect them securely to avoid gas
fume leaks.
- When installing each mounting rubber, use silicon oil to avoid
twisting.
- Temporarily tighten nuts and bolts. Check each part for unusual
interference and mounting rubber
interference, and then tighten them to the specified torque.
- When installing each mounting rubber, avoid twisting or unusual
extension in up/down, front/rear
and right/left directions.
Exhaust Manifold to Exhaust Front Tube
- Securely insert seal bearing (2) into exhaust manifold (1) in the
direction shown.
- Spring
- Nut
- Stud bolt
- Exhaust front tube
CAUTION:
Be careful not to damage seal bearing surface when installing.
- Install spring and tighten nut.
CAUTION:
- Fasten stud bolts to the flange of exhaust manifold side to the
specified torque before installing
nuts.
- Ensure springs are seated correctly on the flange and not sitting
on protrusion (A).
- Be careful that stud bolt does not interfere with mounting hole of
exhaust front tube ( ).
- After installing, check that stud bolt does not interfere with mounting
hole of exhaust front tube.
Exhaust Front Tube to Center Muffler
- Securely insert seal bearing (2) into exhaust front tube (1) in the
direction shown.
- Spring
- Bolt
- Center muffler
CAUTION:
Be careful not to damage seal bearing surface when installing.
- Install spring and tighten bolt.
CAUTION:
- Ensure springs are seated correctly on the flange and not sitting
on protrusion (A).
- Be careful that bolt does not interfere with mounting hole of
center muffler ( ).
- After installing, check that bolt does not interfere with mounting hole
of center muffler.
Inspection
INSPECTION AFTER INSTALLATION
- Check clearance between tail tube and rear bumper is even.
- With engine running, check exhaust tube joints for gas fume leaks and
unusual noises.
- Check to ensure that mounting brackets and mounting rubbers are
installed properly and free from undue
stress. Improper installation could result in excessive noise and vibration.
